Success Event Response Text Empty...

[dainemedia]

Hey,

Whenever I hook into the success event, the response is always empty.

this.$refs.sectionDropzone[0].dropzone.on('success', (file, responseText) => {
    console.log(file, responseText);

    if (responseText) {
        this.getTicket()
            .then(ticket => {
                this.ticket = ticket;

                this.setProgressMeter();
                this.checkProgress(file);
                this.uploadVideo(file, responseText);
            });
    }
});

Here's my PHP code:

<?php

namespace App\Http\Controllers\API;

use Storage;
use App\Models\Video;
use Illuminate\Http\Request;
use Illuminate\Http\UploadedFile;
use App\Http\Controllers\Controller;
use App\Models\CourseChapterSection as Section;
use Pion\Laravel\ChunkUpload\Exceptions\UploadMissingFileException;
use Pion\Laravel\ChunkUpload\Handler\AbstractHandler;
use Pion\Laravel\ChunkUpload\Handler\HandlerFactory;
use Pion\Laravel\ChunkUpload\Receiver\FileReceiver;

class SectionVideoController extends Controller
{
    protected $section;
    protected $video;

    public function __construct(Section $section, Video $video)
    {
        $this->section = $section;
        $this->video = $video;
    }

    public function index()
    {
        $section = $this->section->find(request()->section_id);

        return $section->videos;
    }

    /**
     * Handles the file upload
     *
     * @param Request $request
     *
     * @return \Illuminate\Http\JsonResponse
     *
     * @throws UploadMissingFileException
     * @throws \Pion\Laravel\ChunkUpload\Exceptions\UploadFailedException
     */
    public function store(Request $request) {
        // create the file receiver
        $receiver = new FileReceiver('video', $request, HandlerFactory::classFromRequest($request));

        // check if the upload is success, throw exception or return response you need
        if ($receiver->isUploaded() === false) {
            throw new UploadMissingFileException();
        }

        // receive the file
        $save = $receiver->receive();

        // check if the upload has finished (in chunk mode it will send smaller files)
        if ($save->isFinished()) {
            $file = $save->getFile();

            // save the file and return any response you need, current example uses `move` function. If you are
            // not using move, you need to manually delete the file by unlink($save->getFile()->getPathname())
            $filename = str_slug(basename(time(), '.'.$file->getClientOriginalExtension())).'.'.$file->getClientOriginalExtension();;
        
            // move the file name
            $file->move(storage_path().'/app/media/video/', $filename);

            return storage_path().'/app/media/video/'.$filename;
        }

        // we are in chunk mode, lets send the current progress
        /** @var AbstractHandler $handler */
        $handler = $save->handler();

        return response()->json([
            'done' => $handler->getPercentageDone(),
            'status' => true
        ]);
    }

    public function destroy($id)
    {
        $video = $this->video->find($id);
        $video->sections()->detach(request()->section_id);
        $video->delete();
    }
}

No matter what I do, I cannot get the response after successfully uploading all chunks.

The success event is fired and a can log the file paramter, but the responseText argument is always empty.

Any ideas?

Hi, we have already discussed it, it seems to be drozpzone issue: pionl/laravel-chunk-upload#41

Hi,
How are you?
Thanks for your example :)
It's many helpful for me.
But I am facing a problem.
That is not to get the real extension of uploaded file.

This is your code.

    protected function createFilename(UploadedFile $file)
    {
        $extension = $file->getClientOriginalExtension();
        $filename = str_replace(".".$extension, "", $file->getClientOriginalName()); // Filename without extension
        // Add timestamp hash to name of the file
        $filename .= "_" . md5(time()) . "." . $extension;
        return $filename;
    }

This is some of error codes.

Symfony\Component\HttpFoundation\File\Exception\FileException: Could not move the file "D:\www\csv_upload\storage\app\chunks/./blob-5d603a175d092e872ef1ba4d054994d1.part" to "D:\www\csv_upload\storage\app/upload\blob_007c5fee6abd9db5e02d0a10b3e18336."

......................

If I try to run after change " $extension = $file->getClient OriginalExtension() " to " $extension = $file->getExtension() or "$extension = 'zip(for example...)', it works.
But in the first case, it gets the chunked file extension. (for example .part ).

Please help me.
Thanks. :)

Sorry I have very limited time to help you, but if you get .part then you need to make sure are use the extension when $save->isFinished() is true.
